工程建设过程中会不可避免地遇到地质条件不良或软弱地基,上软下硬的双层地层结构较为常见。本文采用ABAQUS软件,建立本构模型,对浅基础地层结构进行优化的方案进行模拟研究,分别模拟工程中最常用的均质地基和复合地基,将计算得到沉降量、受力情况进行分析,为浅基础的地层结构优化提供参考。 In the course of project construction, it will inevitably encounter poor geological conditions or weak foundations, and a hard and soft double-layered stratum structure is more common. In this paper, the ABAQUS software is used to establish the constitutive model and simulate the shallow ground stratum structure to simulate the simulation. The most commonly used homogeneous foundation and composite foundation in the project are simulated, and the calculated settlement and force conditions are analyzed. Shallow foundation structural optimization provides reference.
